Protective case for an auto-injector

ABSTRACT

The application describes a protective case for an auto-injector. The medicament contained within these auto-injectors can be susceptible to degradation due to exposure to extreme temperatures and light. Thus, one embodiment of the protective case reduces the rate of heat transfer between the internal storage compartment of the case and the external atmosphere by including particularly configured vacuum chambers. Additionally, as auto-injectors become smaller, portability can be desirable. Thus, another embodiment of the protective case includes low-profile cases that allow the user to keep the auto-injector with them, e.g., by attaching the case to a common everyday item.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62/574,405, titled “Protective Case for an Auto-Injector,” which was filed on Oct. 19, 2017, and U.S. Provisional Patent Application No. 62/568,567, titled “Protective Case for an Auto-Injector,” which was filed on Oct. 5, 2017, the disclosures of both of which are herein incorporated by reference in their entireties.

TECHNICAL FIELD

In general, various embodiments of this invention relate to protective cases for drug or biological delivery devices and, specifically, to protective cases forming a vacuum sealed chamber that provides thermal isolation for the enclosed device.

BACKGROUND

The auto-injector market is growing rapidly through an increase in prescriptions, along with new indications for use. Patients are actively seeking solutions to address the anxiety associated with the existing pain points of using protective cases, including poor portability, unwanted attention, and temperature susceptibility.

Existing protective cases address some of the patient's anxieties, but fall short on others and often leave the patients seeking out alternatives. Accordingly, an improved protective case is needed.

SUMMARY

Various embodiments of the invention described herein feature a protective auto-injector case that addresses some of the shortcomings of conventional devices. The auto-injector case can be portable, adaptable, and low-profile. The auto-injector case can also increase the time a patient can maintain their auto-injector device in an adverse climate, as compared to a device without the case. Furthermore, the auto-injector case can allow the patient to prioritize their needs and determine which configuration of the protective case is best for them.

Proposed herein is a protective case adapted for both low and high aspect ratio auto-injectors. As depicted in FIG. 1, the aspect ratio is calculated by dividing the width by the height. The width of the device is measured as the smallest straight-line length on the injection surface of the device that is in contact with a patient's skin during injection (parallel to the injection surface). The height is defined as the largest straight-line length of the device away from the skin during injection (perpendicular to the injection surface). See the ranges for the low and high aspect ratios in the parameter table shown in FIG. 133.

Embodiments of the case may include cases that can be rigid or flexible in nature. The casing material may be metal, thermoplastic (TP), thermoplastic elastomer (TPE), fiber reinforced composite, ceramic, or a combination of materials to provide physical and/or thermal protection for the device. In various embodiments, the case is substantially symmetrical about a horizontal plane and may be uniform about a central axis. The case may be configured in such a means that it is adaptable to everyday use items, and can be attached, whether molded or not, to different cases or objects to increase portability. In addition, certain embodiments may allow the user to carry a single device or multiple devices.

Certain rigid embodiments of the case may contain two vacuum sealed chambers forming an enclosure around the device, to provide thermal protection. The protective case may consist of upper and lower portions of equal or unequal proportions which when mated together form a sealed enclosure. The lower portion may include a double wall, forming a lower vacuum chamber in between, and a lower sidewall flange, where the lower vacuum chamber extends within at least a portion of the lower sidewall flange. The upper portion may include a double wall forming an upper vacuum chamber therebetween and an upper sidewall flange, where the upper vacuum chamber extends within at least a portion of the upper sidewall flange. When the lower portion and the upper portion are mated, the lower and upper sidewall flanges overlap to form a substantially sealed thermally isolated interior cavity for receiving the auto-injector. The pressure in each of the vacuum chambers may be set to reduce the rate of heat transfer and outlined in the parameter table shown in FIG. 133.

In one aspect, an embodiment of the protective case may provide a lower rate of heat transfer between the internal chamber and the external environment or vice versa. In addition to the sealed vacuum chamber, an embodiment may contain an additional passive means of reducing the rate of heat transferred to or from the device. The internal sealed chamber may contain an additional thermal barrier to improve the insulating properties. The additional thermal barrier may consist of a TP, thermoplastic elastomer (TPE), open or closed cell foam layer or combinations of such, which may or may not be one complete piece but consists of multiple pieces that may interlock when the two halves of the case are mated together forming a substantially sealed barrier. The additional thermal barrier may prevent direct contact with the disposed device and the internal cavity wall further limiting the rate of heat transfer. The TP, TPE, or open or closed cell foam pieces may be affixed to the housing through various means including adhesive, mechanical means, or form molded to the housing. The additional insulating barrier may further consist of at least one of a lower insulating barrier disposed about an interior perimeter of the lower sidewall flange and an upper insulating barrier disposed about an interior perimeter of the upper sidewall flange. In addition to the insulating barrier applied to the internal cavity of the case, the internal surfaces of the vacuum chamber may be polished or coated with a reflective layer to reduce the heat transfer through radiation. The coating applied to both surfaces, or at minimum one surface, of the sealed vacuum chamber may act as a reinforcement or aid in the structural integrity of the rigid case in addition to providing a reflective barrier. Furthermore, the case may have an exterior layer or coating consisting of a metal, TP, TPE, fiber reinforced composite, ceramic, or open or closed cell foam or a combination of such materials to aid in thermally insulating the case and disposed device.

The proposed embodiments of the rigid and elastic cases may provide a means of securing the device in a stable manner to eliminate or reduce any motion of the device relative to the case due to external loading or vibration. The method of which the case may secure the device can provide a means to aid in the placement of the device for orientation as well as aid in the removal of the device. The method of which the barrier on the internal chamber of the case may provide an insulating means, it may further assist in securing and stabilizing the device. The insulation barrier may form a cavity that releasably receives portion of the device and can provide the user with accessibility to remove the device from the case. The case may include a lower stabilizing element disposed within the lower portion and/or an upper stabilizing element disposed within the upper portion to support the auto-injector disposed in the interior cavity. The stabilizing element can include a material including a closed cell polymer foam, an open cell polymer foam, rubber, TP, TPE, and/or combinations thereof. The barrier material may be chosen such that its properties aid in thermally isolating the device as well as aid in damping induced vibrations. Furthermore, embodiments may be configured to protect more than one device as well as hold dissimilar devices if deemed necessary. The configuration of holding multiple devices is not limited to a horizontal or vertical layout of stacking, but instead allows for the best optimized method of storing the devices while maintaining a relatively low-profile case.

The sidewall flanges of the upper and lower portions of the thermally protective case may overlap axially, radially, and/or circumferentially to provide an adequately sealed joint. The sealed enclosure may be formed by several different configurations of mates between the upper and lower portion, some of which may include a friction fit, a threaded connection, etc. Embodiments which contain a threaded connection to facilitate the joint between the two halves may provide threads on either corresponding half such that the threads are concealed when connected. In some embodiments the thermal barrier affixed to the inner housings may provide the bond between the two halves of the case. Additionally, when the lower portion and the upper portion are mated together, the interior of the enclosure may be thermally isolated as well as substantially watertight. Embodiments of the rigid case may provide a watertight/water-resistant seal to protect the device from exposure to water or other fluids. The watertight/water-resistant connection between the upper and lower halves of the sealed enclosure may be facilitated by means of a gasket of suitable material, or through the addition of a coating or separate material applied at the joint interface.

An embodiment of the auto-injector case may consist of an ergonomic shape such that it fits easily into an individual's hand and the contours of the case may provide adequate surface area for proper handling. Furthermore, the embodiment may contain an external coating or layering applied to the case. The exterior layer or coating may consist of a metal, TP, TPE, fiber reinforced composite, ceramic, or open or closed cell foam, or a combination of such materials. The external coating may provide the following functionalities; shock absorbing, textured to aid in handling or gripping of the case, contoured surface profiles to aid in handling or gripping, thermal insulation for the device, degradation protection from environmental effects, and structural support for the case integrity. The case can further include an external surface including an embossed surface, a ribbed surface, a grip, and/or combinations thereof. In certain embodiments the insulation barrier may protrude radially from the case to provide a user interface for device removal. Furthermore, the coating or layering may provide a means of applying a label to the external surface of the case.

Examples of the proposed case for an auto-injector include, but are not limited to, embodiments that may provide a means of attachment to everyday items such as keychains, lanyards, wrist straps, cell phones, bikes, etc. Additionally, certain embodiments may include the use of a combination of rigid and elastic cases to provide more accessibility or portability. The attachment mechanisms may include, but are not limited to; a strap, a clip, a pin, a clamp, a mount, a tab forming an eyelet, an adhesive layer, and/or combinations thereof. The method of which the embodiment may provide or allow for a means of attachment between the protective case with a user or object. In various embodiments the protective case forms a second cavity for receiving a second device (e.g., a cell phone and/or a second auto-injector device). In some instances, the second cavity circumscribes at least a portion of the device or auto-injector device.

In some embodiments the case may have an internal power source to allow certain functionalities of the case while storing the device. The case may provide audible instructions relating to the contained device for performing an injection or the stored condition of the device. Additionally, the case may provide connectivity to everyday smart devices for additional functionality. Certain embodiments may allow for the user to monitor the temperature, and location of the case. Additionally, the connected case may allow the user to see if other auto-injector devices are nearby. Additional embodiments may contact emergency responders or next of kin once the auto-injector device has been removed from the case. The case may also provide a display and/or interface for inspection of the case and internal conditions. The case may also provide a means of detecting excessive vibrations or impacts while storing the device. Furthermore, information about the case and contained auto-injector device may be monitored remotely by the manufacturer.

In general, embodiments of the invention are of a protective case for an auto-injector device, for which the case may be rigid, elastic or combination of the two. The method can include the following: (I) a protective case forming a cavity that releasably receives at least a portion of the auto-injector device; (II) the protective case which may contain a lower portion including a double wall forming a lower vacuum chamber therebetween and a lower sidewall flange, where the lower vacuum chamber extends within at least a portion of the lower sidewall flange; and a mating upper portion including a double wall forming an upper vacuum chamber therebetween and an upper sidewall flange, where the upper vacuum chamber extends within at least a portion of the upper sidewall flange; (III) mating the sidewall flanges on the lower and upper portions to form a substantially sealed thermally isolated and or watertight/water-resistant interior cavity for the auto-injector; (IV) and providing a means of attachment for the case to common everyday objects.

DETAILED DESCRIPTION Exemplary Embodiment No. 1 (Vacuum Sealed High-Aspect Ratio Protective Case)

The protective case (1A, 1B, 1C, 1D, 1E) can be constructed of a rigid material of the following compositions: metal, TP, TPE, fiber reinforced composite, ceramic, or a combination of these materials. The protective case is composed of an upper half (1A-400, 1B-100, 1C-100, 1D-100, 1E-100) and a lower half (1A-300, 1B-200, 1C-200, 1D-200, 1E-200), that when mated together form an enclosure (1A, 1B, 1C, 1D, 1E) that is substantially sealed that can provide insulation to the enclosed auto-injector and may be watertight. The upper half (1A-400, 1B-100, 1C-100, 1D-100, 1E-100) and the lower half (1A-300, 1B-200, 1C-200, 1D-200, 1E-200) of the protective case can be composed of a rigid inner and outer wall (1A-305, 1A-404, 1B-103, 1B-202, 1C-103, 1C-104, 1C-203, 1C-204, 1D-102, 1D-202, 1E-102, 1E-202) that form the sealed vacuum chamber (1A-301, 1A-401, 1B-101, 1B-201, 1C-101, 1C-201, 1D-101, 1D-201, 1E-101, 1E-201). The two vacuum sealed halves insulate the disposed auto-injector to limit the heat transfer between the internal chamber and the outside environment. The sealed vacuum chambers are extended to the furthest point (1A-307, 1A-406, 1B-105, 1B-204, 1C-106, 1C-206, 1E-106, 1E-206) at the joints of the two halves to maximize the insulating properties of the case and limit thermal bridging to the interior of the device.

The connection between the upper half (1A-400, 1B-100, 1C-100, 1D-100, 1E-100) and lower half (1A-300, 1B-200, 1C-200, 1D-200, 1E-200) may be a threaded connection (1A-302, 1A-402, 1B-102, 1B-503), a friction fit (1C-102, 1C-202, 1E-106, 1E-206), or any other variation (1D-302, 1D-402) that may provide a sealed connection. The joint between the two halves may provide a watertight connection and in certain embodiments may utilize a gasket (1B-300). Furthermore, the watertight/water-resistant connection may be facilitated through the addition of a coating or separate material applied at the joint interface (1A-303, 1A-403). In certain embodiments the joint between the upper half (1A-400, 1B-100, 1C-100, 1D-100, 1E-100) and the lower half (1A-300, 1B-200, 1C-200, 1D-200, 1E-200) may be facilitated by the thermal barrier (1A-500, 1A-600, 1B-400, 1B-500, 1C-300, 1C-400, 1D-300, 1D-400, 1E-300, 1E-400) affixed to the interior of the housing. The thermal barrier may be affixed to the housing (1A-306, 1A-405, 1B-104, 1B-203, 1C-105, 1C-205, 1D-103, 1D-203, 1E-103, 1E-203) through adhesive, mechanical means, or form molded (1A-501, 1A-601, 1B-401, 1B-501, 1C-301, 1C-401, 1D-301, 1D-401, 1E-301, 1E-401). The sealed connection may be performed via a threaded connection on the insulation sleeve (1B-503) and a corresponding threaded connection on the inside of the top housing (1B-102), such that the threads are concealed once the housings are mated together.

The case may provide additional thermal insulation through a thermal barrier (1A-500, 1A-600, 1B-400, 1B-500, 1C-300, 1C-400, 1D-300, 1D-400, 1E-300, 1E-400) to improve the insulating properties. The additional thermal barrier (1A-500, 1A-600, 1B-400, 1B-500, 1C-300, 1C-400, 1D-300, 1D-400, 1E-300, 1E-400) may consist of a TP, TPE, open or closed cell foam layer or combinations of such, which may or may not be one complete piece but can include multiple pieces that may interlock (1A-503, 1A-603, 1B-402, 1B-502, 1C-302, 1C-402, 1D-302, 1D-402, 1E-302, 1E-402) when the two halves of the case are mated together, forming a substantially sealed barrier. In certain embodiments the device enclosure may be lined with an insulating sleeve (1A-500, 1A-600, 1B-400, 1B-500, 1C-300, 1C-400, 1D-300, 1D-400, 1E-300, 1E-400) formed of one or two pieces, which interlock through stepped ledges or interference fits (1A-503, 1A-603, 1B-402, 1B-502, 1C-302, 1C-402, 1D-302, 1D-402, 1E-302, 1E-402). In certain embodiments the insulation barriers form a well or cradle (1A-502, 1A-602, 1B-403, 1B-505, 1C-503, 1D-303, 1D-403, 1E-303, 1E-403) for stabilizing the device and may dampen any relative motion between the device and the protective case (1A, 1B, 1C, 1D, 1E). Alternatively, the insulation barrier and the stabilizing cradle may be two separate components (1C-500). The material selection for the insulation sleeve and cradle will be such that it minimizes the thermal conductivity and maximizes vibration damping. Additionally, the thermal barrier(s) may protrude from the joint between the upper half (1A-400, 1B-100, 1C-100, 1D-100, 1E-100) and the lower half (1A-300, 1B-200, 1C-200, 1D-200, 1E-200) and provide an interface for the user to separate the halves (1D-304, 1D-404). The insulation barrier may also form a cavity that releasably receives (1B-504, 1E-304, 1E-404) at least a portion of the auto-injector device and provides access for the user to remove the device from the case (1A-304). Furthermore, the insulation barrier or rigid upper or lower halves may provide a means of orientation for the device to be stored and as such removed.

Furthermore, certain embodiments may be configured to protect more than one device (1E) as well as hold dissimilar devices if deemed necessary. The configuration of holding multiple devices is not limited to a horizontal or vertical layout of stacking, but instead allows for the best optimized method of storing the devices while maintaining a relatively low-profile case.

In certain embodiments to aid in the insulating properties of the case, the internal surfaces of the vacuum sealed chambers may be polished or lined with a reflective coating, or similar means to reduce the heat transfer by radiation (1A-308, 1A-407, 1B-107, 1B-206, 1C-108, 1C-208, 1D-105, 1D-205, 1E-105, 1E-205). Additionally, some embodiments may contain an exterior coating (1A-100, 1A-200, 1B-106, 1B-205, 1C-107, 1C-207, 1D-104, 1D-204, 1E-104, 1E-204) or applied layer(s) of dissimilar material or combination of the two, to increase the insulating value of the exterior wall. Furthermore, the exterior coating (1A-100, 1A-200, 1B-106, 1B-205, 1C-107, 1C-207, 1D-104, 1D-204, 1E-104, 1E-204) or applied layer of dissimilar material or a combination of the two, to the exterior may provide a texture or profile to the case to assist the user in handling (1A-101, 1A-201). This exterior coating or layer(s) of dissimilar material or combination of such may perform the following functionalities; improve the ergonomics of the case, aid in reducing the induced vibrations from external loading, contribute to case aesthetics, provide structural support, provide labeling (1A-102), etc.

Furthermore, embodiments of the case may provide a power source (1A-701) to assist in monitoring the conditions of the case both internal and external, and providing connectivity of the case with other smart devices. The case may provide the user with an interface (1A-700) for monitoring internal device cavity and external conditions to better maintain the enclosed device.

In addition to providing a means of monitoring and connecting the case wirelessly to external devices, the case can provide a means of physically attaching to other external objects (1A-104). Additionally, certain embodiments may include the use of a combination of rigid and elastic cases (3H) to provide improved accessibility or portability. In one aspect the combination of the rigid and elastic cases may provide a means to affix the case or combination of cases to such everyday items like a backpack, lanyard, bike, keys, etc. The attachment mechanism may include a wrist strap, a wrist band, a clip, a tether, a necklace, a pin, a clamp, a mount, a tab forming an eyelet, an adhesive layer, a hand grip surface, and/or combinations thereof.

The case may be composed of two sealed vacuum chambers (2A-101, 2A-201, 2B-101, 2B-201) of proportional or nonproportional size. In one embodiment, the vacuum sealed chamber is composed of two parts (2A-103, 2A-104, 2A-203, and 2A-204).

The connection between the upper and lower halves may be a threaded connection, a frictional interference fit (2A-102, 2A-202, 2B-102, 2B-202), or any other variation that may provide a sealed connection. The joint between the two halves may provide a watertight/water-resistant connection and in certain embodiments may utilize a gasket. Furthermore, the watertight/water-resistant connection may be facilitated through the addition of a coating or separate material applied at the joint interface. In certain embodiments the joint between the upper half (2A-100, 2B-100) and the lower half (2A-200, 2B-200) may be facilitated by the thermal barrier (2A-300, 2A-400, 2B-300, 2B-400) affixed to the interior of the housing. The thermal barrier may be affixed to the housing (2A-105, 2A-205, 2B-104, 2B-204) through an adhesive, mechanical means, or form molded (2A-301, 2A-401, 2B-301, 2B-401). The sealed connection may be performed via a threaded connection on the insulation sleeve and a corresponding threaded connection on the inner top housing, such that the threads are concealed once the housings are mated together. Similarly, the connection may be performed using a friction fit or interference connection (2A-302, 2A-402, 2B-302, 2B-402).

The case may provide additional thermal insulation through a thermal barrier to aid in the insulating properties (2A-300, 2A-400, 2B-300, 2B-400). The additional thermal barrier may consist of a TP, TPE, open or closed cell foam layer or combinations of such, which may or may not be one complete piece, but consists of multiple pieces that may interlock (2A-302, 2A-402, 2B-302, 2B-402) when the two halves of the case are mated together, forming a substantially sealed barrier. In certain embodiments the device enclosure may be lined with an insulating sleeve (2A-300, 2A-400, 2B-300, 2B-400) formed of one or two pieces, that interlock through stepped ledges or interference fits (2A-302, 2A-402, 2B-302, 2B-402). In certain embodiments the insulation barriers form a well or cradle (2A-303, 2A-403, 2B-303, 2B-403) for stabilizing the device and dampen any relative motion between the device and the protective case. Alternatively, the insulation barrier and the stabilizing cradle may be two separate components. The material selection for the insulation sleeve and cradle will be such that it minimizes the thermal conductivity and maximizes the shock absorption properties. Additionally, the thermal barrier(s) may protrude from the joint between the upper and lower halves and provide an interface for the user to separate the halves. The insulation barrier may also form a cavity that releasably receives at least a portion of the auto-injector device and provides access for the user to remove the device from the case. Furthermore, the insulation barrier or rigid upper or lower halves may provide a means of orientation (2A-304, 2A-404) for the device to be stored and as such removed.

Furthermore, certain embodiments may be configured to protect more than one device as well as hold dissimilar devices if deemed necessary. The configuration of holding multiple devices is not limited to a horizontal or vertical layout of stacking. The configuration allows for the method of storing multiple auto-injector devices while maintaining a low-profile case.

In certain embodiments to aid in the insulating properties of the case (2A, 2B), the internal surfaces of the vacuum sealed chambers (2A-101, 2A-201, 2B-101, 2B-201) may be polished or lined with a reflective coating (2A-108, 2A-208, 2B-107, 2B-207), or similar means to reduce the heat transfer through radiation. Additionally, some embodiments may contain an exterior coating or applied layer(s) of dissimilar material or combination of the two, to increase the insulating value of the exterior wall (2A-107, 2A-207, 2B-106, 2B-206). Furthermore, the exterior coating or exterior layer of dissimilar material or combinations of the two, to the exterior may provide a texture (2A-107, 2A-207, 2B-106, 2B-206) or profile to the case to assist the user in handling or gripping. This exterior coating or layer(s) of dissimilar material or combination of such may perform the following functionalities; increase the ergonomics of the case, aid in reducing the induced vibrations from external loading, assisting in case aesthetics, provide structural support, provide labeling, etc.

Furthermore, embodiments of the case may provide a power source to assist in monitoring the conditions of the internal device cavity and external environment and providing connectivity of the case with other smart devices. The case may provide the user with an interface for monitoring internal device cavity and external conditions to better maintain the enclosed device.

In addition to providing a means of monitoring and connecting the case wirelessly to external devices the case can provide a means of physically attaching the case to other external objects. Additionally, certain embodiments may include the use of a combination of rigid and elastic cases to provide a more accessible or portable means (3H). In one aspect the combination of the rigid and elastic cases may provide a means to affix the case or combination of cases to such everyday items like a backpack, lanyard, bike, keys, etc. The attachment mechanism may include a wrist strap, a wrist band, a clip, a tether, a necklace, a pin, a clamp, a mount, a tab forming an eyelet, an adhesive layer, a hand grip surface, and/or combinations thereof.

Exemplary Embodiment No. 3 (Protective Cases that Enable Increased Portability of Auto-Injectors)

Embodiments of a protective case may not be required to possess thermally insulating properties (3A, 3B, 3C, 3D, 3E, 3F, 3G, 3H), but rather provide physical protection and a means of increased portability for an auto-injector. The protective case may form a cavity (3A-100, 3B-100, 3B-101, 3C-100, 3D-100, 3E-100, 3F-303, 3F-403, 3G-201, 3H-100) that releasably receives at least a portion of the auto-injector device. Embodiments shown in FIGS. 98-132 include but are not limited to different cases which may attach (3A-102, 3B-103, 3C-101, 3C-103, 3D-101, 3D-103, 3E-104, 3E-105, 3E-106, 3G-102, 3H-103) to everyday objects and allow for the auto-injector to be in close proximity to the user wherever they are. The protective cases may provide a manner of protection by damping any incurred forces or vibrations through material selections. Embodiments of a non-vacuum sealed case may be constructed of a metal, TP, TPE, fiber reinforced composite, ceramic, or combinations of similar materials. Certain embodiments may also provide a watertight/water-resistant or water-repellant enclosure (3F-101, 3F-201) around the device and may facilitate this watertight/water-resistant seal by means of a gasket or through the addition of a coating or separate material applied at the joint interface.

Certain embodiments of a protective case may provide a means of attaching the case to common everyday objects or similarly other protective cases (3A-102, 3B-103, 3C-101, 3C-103, 3D-101, 3D-103, 3E-104, 3E-105, 3E-106, 3G-102, 3H-103). The attachment mechanisms may include but are not limited to; a strap (3E-106), a clip, a pin, a clamp, a mount (3H-103), a tab forming an eyelet (3A-102, 3B-103, 3G-102), an adhesive layer (3A-103, 3G-103), and/or combinations thereof. One embodiment for the case may contain an eyelet (3A-102, 3B-103, 3G-102) or similar geometry to provide a means of fastening the case to another object. The eyelet (3A-102, 3B-103, 3G-102) or similar feature may be formed through a molded, adhered, or formed feature on the protective case. Alternatively, the case may provide a molded or formed strap (3E-106) or a similar feature. The strap (3E-106) may provide a means of adjustment to accommodate a desired circumference. This may be accomplished by of adjustment holes (3E-104), the adjustment holes may be fixed by means of a buckle (3E-105) or similar manner to fasten the case. In addition, the protective case for the auto-injector may have an adhesive (3A-103, 3G-103) applied to one surface for fixating the case to another object. Furthermore, one embodiment of the protective case for containing an auto-injector may allow for the integration of a cell phone, or similar electronic device, for better adaptation and meshing with the user's daily routine (ex: 3C-101, 3C-103, 3D-101, 3D-103) Further embodiments may be adapted to store one or more devices (3B-101, 3D-100). The case may hold a single device or multiple devices whether similar form or not. The configuration of holding multiple devices is not limited to a horizontal or vertical layout, but the best optimized method of storing the devices while maintaining as low a profile case as possible.

Embodiments of the protective case may contain a housing which receives the auto-injector (3A-100, 3B-100, 3B-101, 3C-100, 3D-100, 3E-100, 3F-303, 3F-403, 3G-201, 3H-100) and may stabilize the auto-injector by means of a feature molded or formed into the housing (ex: a ridge, lip, etc.) (3A-101, 3B-102, 3C-102, 3D-102, 3E-101, 3G-101, 3H-100). The ridge maintains constant communication between the device and the housing at all times until removed for use. Furthermore, the geometry of the housing may be such that once the device is disposed within, the housing is placed under a state of stress and as such maintains constant communication with the device (3C-104). The housing may or may not enclose all sides of the auto-injector (3A-106, 3B-106, 3C-106, 3D-104, 3E-102, 3F-303, 3F-403, 3G-201, 3H-100) whilst providing a means to easily and rapidly remove in times of need (3G-106). In addition, the ridge, lip, etc. (3H-104). of the housing ensures that any external vibrations will not allow the auto-injector to become separated from the housing (3A-100, 3B-100, 3B-101, 3C-100, 3D-100, 3E-100, 3F-303, 3F-403, 3G-201, 3H-100). One embodiment (3G) may contain multiple materials to provide a layering effect to protect and conceal the device. In certain embodiments the housing may provide a means of orienting the device during storage using molded or formed shoulders or other similar features. In certain embodiments the housing may also be adjustable to accommodate different sized auto-injectors (3H).

Certain embodiments may provide a textured or contoured exterior surface (3A-105, 3B-105, 3C-105, 3D-105, 3E-103, 3F-104, 3F-204, 3G-202, 3G-105) by means of a coating or applying additional materials, or molded features, or a combination of such. In some embodiments the external coating or textured surface may be accomplished by layering materials (3G). The exterior surface texture or contours may aid in increasing the ergonomics or handling of the case, or likewise in assisting the user in removing the auto-injector (3G-106). Furthermore, this exterior coating or layer(s) of dissimilar material or combination of such may perform the following functionalities; increase the ergonomics of the case, aid in reducing the induced vibrations from external loading, assisting in case aesthetics, provide structural support, provide labeling (3G-302), etc.

Furthermore, these cases may provide a means to be able to accommodate the auto-injector alone or incorporate other protective cases in combination as well (vacuum sealed or not) (3H-100, 3H-101, 3H-104, 3H-105). Embodiments of certain protective cases may present themselves with a feature to allow for the mounting and joining to other cases. Adjustments for securing various sized auto-injectors and cases may be accomplished through, but not limited to, clips, straps (3E-106), molded features (33-106, 3H-103), or other suitable means which can securely fasten one to the other.

Additional, embodiments of the case may provide a way of moving the auto-injector relative to the point of fixation (3H-103). This relative movement may be facilitated by but not limited to a ball joint and receiver (3H-102). The ability to move the auto-injector relative to the fixation point may allow the user better access, and improved ergonomics for handling and accessibility.

Certain embodiments of the case may provide a power source to assist in monitoring the conditions of the case both internal and external as well as the connectivity of the case with other smart devices. The case may provide the user with an interface for monitoring internal and external conditions to better maintain the enclosed device.
